I know we got the right belt we doubble checked it from the appliance store when we bought it and the numbers matched up on the old belt.. the model number is FWT647GHSO...the new belt is tight , it just makes a terrible noise, my father was here tonight and said the berrings are gone and it really wobbles alot when in the spin cycle, while running it to show my dad (old appliance tech) he heard it and then the belt flew off again from the wobbleing..
